Ezekiel 4:6-8

6“After you have finished this, lie down again, this time on your right side, and bear the sin of the people of Judah. I have assigned you 40 days, a day for each year.

7Turn your face toward the siege of Jerusalem and with bared arm prophesy against her.

8I will tie you up with ropes so that you cannot turn from one side to the other until you have finished the days of your siege.
